It is a term that comes from gender-critical feminism but this is a mainstream view in the UK, there's nothing extremist about it. It's effectively a sensible middle ground between anti-trans parochialism and trans rights dogma. Even the term "trans-identifying male" is a middle-ground compromise, to avoid calling them men and to not cede the argument by referring to them as women. In my experience, the most thoughtful and well-considered discussion on this topic has been with gender-critical feminists who have thought critically about their perspective and have it based in the material reality of sex.
